[Arjen Markus] This page will describe the geometry package Christian Heide Damm started and that we are now developing in cooperation. 

The idea is simple - define points, vectors, planes, lines, line segments and so on via "qualified" lists. Define operations on these lists like, calculate the distance between points, project a line on a plane.

Such a package is useful for applications involving interactive design/drawing, "CAD"-like applications, ...

The page should describe:

   * What objects do we want?
 
   * Representation of these objects as lists

   * Operations on these objects

----
[AK]: Conversions of such objects into other formats ? POVRay for example ? Is the stuff 2D or 3D ?
